Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

AWS::Cassandra::Keyspace ReplicationSpecification

You can use ReplicationSpecification to configure the ReplicationStrategy of a keyspace in Amazon Keyspaces.

The ReplicationSpecification property applies automatically to all tables in the keyspace.

To review the permissions that are required to add a new Region to a single-Region keyspace, see Configure the IAM permissions required to add an Amazon Region to a keyspace in the Amazon Keyspaces Developer Guide.

For more information about multi-Region replication, see Multi-Region replication in the Amazon Keyspaces Developer Guide.
